The k-Means cluster analysis is one of the simplest and most common procedures for cluster analysis. Thus, the k-Means method is one of the most widely used methods. It is a partitioning procedure that is particularly suitable for large amounts of data.

The k-means method tries to distribute the data points among the k clusters in such a way that the sum of the distances from each point to the respective cluster centroid is minimised.

And here is the online k-Means Cluster Calculator on DATAtab:

Why did you decide to choose 2 instead of 3 clusters ?, to me the 3 clusters looked neater on graph.

And is due to this that many groups then take the statistic and assume causation out of correlation as if it was a causation truth and not a result of the few variables being analysed.
